Abstract

fetched live from OpenAlex

This research examines the thermal behavior and sintering characteristics of hydroxyapatite (HAp) composites with yttria-stabilized zirconia (YSZ) and titanium using the spark plasma sintering (SPS) method. This study uses simultaneous thermal analysis (STA) to investigate the decomposition behavior of composites. During the sintering process, data on displacement, temperature, time, and current were recorded. A key challenge encountered was the fracture and crushing of the samples after the sintering process. The results show that the decomposition temperature of pure HAp (sample 0-100) occurs around 800 °C. In contrast, adding 4% titanium and 6% YSZ to the sample composition increases the decomposition temperature above 1000 °C. A further increase in YSZ content, up to 31%, leads to a decomposition temperature of approximately 1000 °C. These findings show that the presence of titanium and its conversion to TiO2, together with YSZ, increases the stability of the composite materials and thus reduces HAp decomposition and affects the thermal behavior of the sintered samples.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
